You can put this solution on YOUR website!
Well the volume of a cylinder is V=π(r^2)h\r
\n" ); document.write( "\n" ); document.write( "If the diameter and the height are the same than the radius is half of the height.\r
\n" ); document.write( "\n" ); document.write( "The diameter , d, is 2r, r being the radius, if the height and diameter are the same, than h=2r too\r
\n" ); document.write( "\n" ); document.write( "Therefore:\r
\n" ); document.write( "\n" ); document.write( "V=π(r^2)2r\r
\n" ); document.write( "\n" ); document.write( "I hope this helps!
